This is the OS4 API emulator for MorphOS. It is not complete but quite
a number of OS4 native programs run.

   What is new in 2.0
   ------------------

   · Enhanced newlib.library
   · Implements OS 4.1 64bit DOS functionality
   · Implements OS 4.1 Exec functionality
   · Implements OS 4.1 Picasso96 functionality
   · Improved general compatibility
   · Fixed ELF loader

   64bit DOS calls are supported in MorphOS 1.x but file size is limited to 2GB.
   In MorphOS 2.x native 64bit DOS calls are used.

   AltiVec is supported only in MorphOS 2.

   Old ELF loader had lots of bugs and certain relocations in executables were
   calculated incorrectly causing runtime crashes. It also supports more
relocation
   types and "file not executable" problem should be gone now. Dynamic linking
is
   not supported.

   Picasso96 now implements p96WritePixelArray() and emulation is now complete.

   Warp3d.library allows running only some OS4 native Warp3D programs and it
only covers
   functions up to version 4. Warp3D Nova extensions are not supported.

   Application.library is only experimental and is included for testing purposes
only.

Usage:

Use supplied installer script or copy os4kernel.library and os4loader.library
to LIBS: and OS4Emu launcher tool and PatchLoadSegOS4 to C:.

To run OS4 native software you type "OS4EMU <os4exe> <params>" or run
PatchLoadSegOS4 in User-Startup. Once patch is running you can start
OS4 native software directly from Ambient.

When using OS4EMU launcher you can use "??" to get help from OS4 native
program.

   Support for ClassAct/Reaction was introduced in version 1.4.

   The string "installed version" mean library version depends on
   your MorphOS installation. Version number 51.0 doesn't mean all
   function calls are implemented or supported.

   There are now 61 supported interfaces in total.
